Ketchup actually started out as a fish sauce and somehow evolved into the much more widely-consumed condiment we know today. Early recipes of ketchup contained sodium benzoate -- which was banned in the 1906 Pure Food and Drug Act. That ban led to other formulations which contained vinegar as a preservative and used ripe tomatoes. Here are just a few more fascinating factoids about this tangy, thixotropic, tomato-based foodstuff.
